Ecommerce (Amazon and Shopify)
Finbryn splits Amazon and Shopify settlement payouts into sales, marketplace fees, refunds and reserves inside Xero or MYOB, so GST reporting matches the store, not one lump deposit. We track landed cost by SKU, watch the A$75,000 GST turnover threshold, and prepare BAS figures for TPB-registered review and lodgement.

Reviewer's note
Software is up on last month after two seats were added mid-month. Revenue includes one milestone invoice that will not repeat next month.

Exceptions report
Where the books usually hurt
Marketplace payouts land as one lump sum that hides sales, fees, refunds and reserves
Cost of goods sold gets estimated instead of tracked by SKU and inventory location
Sales tax nexus creeps across states as revenue grows and nobody notices until a notice arrives
Multiple sales channels mean multiple ledgers that never quite reconcile to the bank
A settlement deposit is not a GST figure
Amazon and Shopify pay Australian sellers one net amount that already has marketplace fees, refunds, advertising spend and a reserve netted out of it. Recording that single deposit as sales overstates the GST a seller thinks they have collected and understates the fees and refunds sitting underneath it. Once the deposit is unpicked into its parts, the GST-inclusive sales figure that actually belongs on a BAS looks very different from the number that landed in the bank.
The A$75,000 threshold and quarterly BAS
A business only has to register for GST once its GST turnover reaches A$75,000 in a 12-month period, and registration is due within 21 days of crossing that line. Below it, a seller can choose to stay unregistered and simply not charge GST, which changes how Amazon and Shopify fees and any input tax credits are treated in the books. For a fast-growing store this threshold gets crossed mid-year, often without anyone noticing until a BAS is due. We track GST turnover against the threshold as part of the monthly close, not as a year-end surprise.
Once registered, most sellers lodge BAS quarterly, with the 2026-27 due dates falling on 28 October 2026, 28 February 2027, 28 April 2027 and 28 July 2027. Finbryn prepares the GST figures behind each BAS from reconciled sales, fees and refunds, ready for review and lodgement by a TPB-registered practitioner.
Landed cost, not a blended margin
Cost of goods sold gets tracked by SKU using supplier invoices and freight documentation, rather than one average cost percentage applied across the whole catalogue. A margin problem on one product line stays visible instead of disappearing into a number that looks fine on average.
Working with Finbryn
Your Xero or MYOB file stays yours; nothing moves onto a platform you cannot open if the arrangement ends. A named pod handles the account, and any change to that pod comes with a recorded handover memo. Books are reconciled weekly and closed by business day five, with pricing published on our pricing page and terms set out in your engagement letter. Sellers coming off a year of unreconciled bank feeds are usually quoted a separate catch-up project, priced on transaction volume, before moving onto ongoing monthly bookkeeping. Every file goes through senior principal review before it reaches you.
Questions
Frequently asked questions: Ecommerce (Amazon and Shopify)
Do you work with both Xero and MYOB?
Yes. Most Australian sellers we work with run one or the other, and A2X or Link My Books feeds settlement data into either file.
How do you track the A$75,000 GST registration threshold?
GST turnover is checked against the threshold each month as part of the close, so registration is flagged before it becomes overdue, not after.
Can you prepare BAS figures for a business that is not yet GST registered?
Yes. Books are kept consistently either way, and the GST treatment is adjusted once registration actually happens.
Who actually lodges the BAS?
We prepare and reconcile the figures. Lodgement itself is handled by a TPB-registered practitioner under a documented supervision arrangement, or by your own registered agent if you already have one.
Do you handle inventory value alongside the sales side?
Yes, where a seller wants it. Landed cost by SKU and stock movements can be tracked inside the same file, so gross margin and GST reporting are built from the same reconciled numbers.
Do you work with A2X or Link My Books?
Yes, either one, depending on which the seller already has connected to their marketplace and accounting software.
Can you track cost of goods sold by product?
Yes, when landed cost and inventory data are available from the seller's supplier records or 3PL.
What are the common bookkeeping challenges for a ecommerce (Amazon and Shopify) business?
Beyond the basics, sales tax nexus creeps across states as revenue grows and nobody notices until a notice arrives and multiple sales channels mean multiple ledgers that never quite reconcile to the bank come up often in this industry. We build the chart of accounts and reconciliation process around those specific patterns rather than a generic template that ignores how the business actually operates.
What software do you support for ecommerce (Amazon and Shopify)?
We work inside Shopify and Amazon Seller Central, along with the other tools listed on this page that are common in the ecommerce (Amazon and Shopify) industry. If you have no file yet, we set one up in your name so you own it from day one.
